The Gateworks System Controller on Ventana boards has the ability to
disable the board's primary power supply until the RTC hits a specific
time. When sleeping a button-down event on the GSC user pushbutton will
wake the board before it's wake time has been reached. This feature is
referred to as GSC sleep.
Add a command to invoke sleep mode for a specified number of seconds.

This adds information about the Gateworks System Controller to the gsc command
such as the firmware version, firmware CRC and status of the GSC watchdog
(if its enabled and if its tripped).
Additionally the 'gsc wd' command can be used to enable or disable the
watchdog with the following usage:
gsc wd enable [30|60]
gsc wd disable
Note that the GSC registers are battery-backed by the GSC coincell so once
eanbled, they remain enabled across power-cycles or until either the GSC
firmware has been updated or FLASH has been re-programmed by the Gateworks
JTAG adapter.

Add a new voltage rail added in various -C revision PCB's.
Additionally make VDD_CORE, VDD_SOC, and VDD_IO2 common as all Ventana boards
have those.

The min/max of each depends not only on board but on CPU. Simplify by removing
this rarely needed and difficult to maintain feature and just display the
rails and their values.

The Gateworks System Controller EEPROM config is flash based. Add a delay
following writes to avoid errors on back-to-back writes.

Gateworks Ventana is a product family based on the i.MX6. This
patch adds support for all boards in the Ventana family. Where
possible, data from the boards EEPROM is used to determine various
details about the board at runtime.
